IMPLEMENT vE ren/1' This invention relates to improvements in the constructlon of farm mplements and is more particularly directed to provisionof an adjustable threehorse fer use with cultivatorsof the two-row type p The main 7 purpose of the invention is "to two are pivotally "connected for movement vertically, through the use of which the front of theimplement frame; usually a straddle row cultivator, can be readily adjusted with respect to the draft frame to raise and lower the'front ends of'theculti vator beams to maintain them ,in parallelrelation to the ground when 'thebeam's ar adjusted to change thede pth of;cultivation',

This main object and other minor objects are"attained by the organization and details of construction, or equivalents thereof,; hereinafter more specifically"described and claimed;

' whichthey diverge forwardly and "arejse Referring to the drawingv accompanying 7 the spec fication,

Fig. 1 is a plan v1ew'of the forward, cen-' tral'fportion of a two row, cultivator; V

Fig. .2 is a-longitudinal', Vertical section cultivator beams and supports therefor added; and

Fig. 3 is an enlargeddetail vie on line 33, Fig.2, of the: adjustable connection between the implement and drafts frame. 1

The inventlon 1s shownpon the drawing as applied to a two row cultivator, the 'n'u-w ing the wheels 15. Longitudinally; extend? ing" frame bars 16, which carry the drivers seat, are secured beneath the bar 12 from cured to the transverse bar 11, asclearly shown in Fig; 1. This frame, carries the V usual cultivator beams, one of which; is

" oted'on the arms of the usualarches," shown are suspended'from the-frame iineans of way between them'vvhere their; converged ends are secured to a pivot member hav ng an arm 26 which isconnected by'm'eans' of' a' member the bars 25 areextended rearward 1y at a sllght inclination downward as-indicatedat' 29 and-a roller 30 is journaled on a pin 31 connecting the endsi'of the bars. i

For cooperation with therollerl3Ocarried 'bythe extension 29 there is pivoted, between ears on' a bracket32; one end of a; depending cam lever 33, the lower end of1which has pivoted toit azrod 34: connecting with an drivers seat. The 'camlever '33 is preferably formed Wltllfl transversely extending'ar- -actuatinglever 35 pivoted on the seatsup porting bars" 16 at'a; point convenient to the I cuate slotf36 which receives the roller 30, the

bars of extension 29 straddling "the lever;

The slot 363s centered onan'axiseccentrictothe pivot of-lever 33 and its relationto the extension 29 is such thatactuationgfiof the lever vvill ,cause angular movementsbetween the draft "frame andimplementframe';

The draft frame structure above Y de= 95. it being understood that thefusual single 2 3 scribed is intended asa" three-horsehitoh,

trees are to be provided andthat'oneh rse will'b'e positioned-betweenthe' thills 22 and.

the other horsesonthe outersides'thereo'f. The thills will; therefore, be supported by thehorses, and-movement imparted to lever '33 through actuation of hand lever 85*will cause angular movement between 'thejtwo frames on the pivots"2127-' 'therebywraisk ing or loweringthe front portion of the-implement frame and the-front ends of-the To the foregoingstructure,which is mere 7 lydescribed -by'way of example, as the in ventionv'maybe-used with any similar frame construction, there is pivoted adraft frame comprising a'pair of' draft members 'ffor thills 22 "which are connectedto the front- 7 bar 1 O of the frame by means of brackets,

23am; pivot pins 24. The draft members 22 arefconnected and braced by a pair of dmgonall o extending bars 25 which are con nected' to intermediate'portions'ofthe thills' 22' and converge inwardly to a 'poin't mid beams 17, this adjustment being necessary to level the beams and compensate for any change in depth of cultivation effected by raising and lowering the rear ends of the cultivator beams Which carry the cultivating tools or shovels.

It will-"becleai" from the foregoing description that the invention provides a. sim-v .ple form of mechanism for effecting exact changes in adjustment between .,adraft and implement frame, and, While the preferred form of; the invention; is here disclosed, fit 2* is evident that modifications: areposslb'le-i Withoutdeparting, from. the: gistof t lieinvention as defined in: the.- foll'ojwingg claims. 7 f What. is; claimed asnew ls: 7 The combination with: an implement frame; and a; draft structure pivotedtogether at; the forward end of the implement :i-fra-me' forangularadjustment vertically, of means: for, effecting saidadjustment comprising a depending leverjpivotedon the frameand 1 formedflwith. atransversely extending cam. track, means. for swinging. thelever', and
